2010-10-21ceph: factor out libceph from Ceph file systemYehuda Sadeh1-20/+0
This factors out protocol and low-level storage parts of ceph into a separate libceph module living in net/ceph and include/linux/ceph. This is mostly a matter of moving files around. However, a few key pieces of the interface change as well: - ceph_client becomes ceph_fs_client and ceph_client, where the latter captures the mon and osd clients, and the fs_client gets the mds client and file system specific pieces. - Mount option parsing and debugfs setup is correspondingly broken into two pieces. - The mon client gets a generic handler callback for otherwise unknown messages (mds map, in this case). - The basic supported/required feature bits can be expanded (and are by ceph_fs_client). No functional change, aside from some subtle error handling cases that got cleaned up in the refactoring process. Signed-off-by: Sage Weil <sage@newdream.net>
2009-11-07ceph: make object hash a pg_pool propertySage Weil1-0/+2
The object will be hashed to a placement seed (ps) based on the pg_pool's hash function. This allows new hashes to be introduced into an existing object store, or selection of a hash appropriate to the objects that will be stored in a particular pool. Signed-off-by: Sage Weil <sage@newdream.net>
2009-11-07ceph: make CRUSH hash functions non-inlineSage Weil1-0/+1
These are way to big to be inline. I missed crush/* when doing the inline audit for akpm's review. Signed-off-by: Sage Weil <sage@newdream.net>
